SYRINGE..

SEECFICATION forming* part Of Letters Patent N 678,568, dated July 16, 1901.

Application filed December 7, 1899. Serial No. 739,553. (No modell) To if/ZZ whom t may concern: y

Be it known that LRIGHARD JOHN HUeHns, a citizen of the United States, residing at Dedham, in the county of Douglas and State of Visconsin, have invented a new and useful Syringe, of which the following is a specilication.

This invention relates to syringes; and it has for its object to provide asyringe in which the Walls of that portion of the anatomy treated will be held away from the outer surface of the syringeetube and in a position to receive the full benefit of the syringing operation. Thus in contradistinction of the usual construction of a syringe in which the discharge of the syringing liquid is liable to be along only a portion of the Wall undergoing treatment, the effective syringing being confined almost entirely to that portion of the anatomy directly in advance of and surrounding the discharge end of the syringe. l

The figure of the drawing represents a perspective view of a syringe embodying the features of the invention.

The syringe-tube 2O hasaglobular discharge end 2l, provided with radial perforations and extending longitudinally of the tube 20, and on opposite sides thereof are the legs 22 and 23 of a U-shaped spreader element. A second U-shaped spreader element has its legs 2o' and 27 disposed at opposite sides of the tube 2O and in a plane at right angles to the plane of the first-named spreader element, the web 28 thereof passing over and transversely of the end of the tube 2O and within the inclosure of the iirst-named. spreader element. The legs of the spreader elements are connected with the 'tube 2O through the Inedium of the spiders 29 and 30, the arms of which are perforated and are correspondingly alined to receive the legs of the spreader elen ments.

The application and operation of this forni of the invention will be evident, the syringing fluid contacting freely with the Wall of the anatomy continuously from the inner ends of the spreader element to the outer limit of said wall, excepting on the lines of engagement of the legs of the spreader elements with the Wall. By giving the parts a rotary or an oscillatory motion either continuously or intermittently the contact of the syringing liquid may be continuous of the periphery of the wall.

Having thus described my invention, what I claim is- In a syringe the combination with an elongated imperforate tubular feeder having a rear open end and a front spherical head perforated completely over its entire surface, a pair of U -shaped spreaders arranged in planes at right angles to each other and having their bowed ends crossed in advanceof the said spherical head of the feeder, the legs of each spreader being parallel to each other, and two spiders having central sleeves and four radial arms with terminal sleeves,the central sleeves of the spiders being xed on opposite .extremities of the feeder and the sleeves at the terminals of the arms fitted on the legs of the spreaders whereby the feeder is held in cen` trai position Within the spreaders.

In testimony that l claim the foregoing as my own 1 have hereto affixed my signature in the presence of two witnesses.
